In addition to a Sample Prep Set the products of the Chromatographic Platform are required.
5-Hydroxyindoleacetic Acid (5-HIAA)
Homovanillic Acid (HVA)
Vanillylmandelic Acid (VMA)
MassChrom® Biogenic Amines/Metabolites in Urine - LC-MS/MS
With autosampler vials, for manual sample preparation
Clinical Relevance
This Sample Prep Set allows the quantitative determination of vanillylmandelic acid (VMA), homovanillic acid (HVA), 5-hydroxyindoleacetic acid (5-HIAA) in patient urine samples by LC-MS/MS. It is used for the diagnostics of neuroblastoma and carcinoid tumours.
Product advantage
- Simple and fast sample prep consisting of 2 pipetting steps and subsequent injection
- Isotopically labelled internal standard for each analyte
- 6PLUS1® Multilevel Calibrator Set and MassCheck® controls ensure high precision of results
This Sample Prep Set encompasses all required components for an efficient and fast sample preparation.
There is also a method using collection plates (80800/96 & 80800/480) as well as the corresponding fully automated workflow solution available for laboratories with a higher sample throughput.
